How many faradays of electricity are required to liberate 9g aluminium? Posted by staff | Jul 31, 2018 | Chemistry | 2 | How many faradays of electricity are required to liberate 9g aluminium? (AI = 27) A. 0.1 B. 0.3 C. 1.0 D. 2.7 E. 3.0 Correct Answer: Option C C. 1.0

ojasweb on September 7, 2018 at 1:43 pm (AL = 27) Al3+ + 3e- = Al 27g of Al required 3 x 96500 9g will require: (3x96500x9)/27 Ans=96500C of electricity. 1 Faraday = 96500 therefore the answer is 1. Reply

Pls show me the workings

(AL = 27)

Al3+ + 3e- = Al

27g of Al required 3 x 96500

9g will require: (3x96500x9)/27

Ans=96500C of electricity.

1 Faraday = 96500

therefore the answer is

1.
